Question

a triangular prism has a height of 11 and a base with the following measurements. all dimensions are meters. what's is the value of B?14m^27m^277m^28m^2

Answer 1

For this problem we use the formula for the area of a traingle ( since the base is one):

$\begin{gathered} B=\frac{1}{2}base\cdot height \\ \text{susbtituting } \\ B=\frac{1}{2}4m\cdot3.5m=2m\cdot3.5m=7m^2 \end{gathered}$

Answer: 7 m^2
